Synthesis and Polymerization of Fluorinated Sulfur Modified Nitroso Rubber
Abstract
Efforts to prepare CF3SNO and SF5NO continued (see AD0437996). The new monomer CF3SCF=CF2 was prepared and its reactivity with CF3NO and CF2=CF2 examined. An attempt to homopolymerize CF3SCF= CF2 using cobalt-60 irradiation gave a very low conversion. Ultraviolet irradiation of a mixture of CF3SCF=CF2 and ClNO in the gas phase gives a blue liquid, probably either CF3SCFClCF2NO or CF3SCF(NO)CF2Cl. Attempts to obtain copolymers from both thiocarbonyl fluoride and perfluorothioacetone were not successful. The intermediate CF3SCl was prepared by an alternate synthesis involving the gas-phase irradiation of a mixture of CF3SSCF3 and chlorine.
